Praxis Works SRAM BB Converter 68mm GXP OSBB
The Praxis Works SRAM BB Converter 68mm GXP OSBB is designed to be a proper bottom bracket (BB) for installing SRAM GXP cranks in Specialized’s OSBB road frames. Praxis Work's patent pending design keeps the cartridge bearings outboard of the frame, right on SRAM spec for greater rigidity that is free of frame/c-clip tolerance issues that other systems deal with.
Simply press in the longer non-drive-cup, then the shorter drive cup threads into it. As the drive cup threads in, Praxis Work's trademark Collet system expands to a precise limit evenly dispersing pressure for a super tight fit.
With both cups connected and Praxis Work's collet set exactly to spec, there is no chance the bearings can come out of alignment or wiggle out of the frame. This design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies.
